PFSA (Perfluorosulfonic Acid) membranes are the most widely used type of cation exchange membrane in high-performance electrochemical systems. They are defined by a "Teflon-like" hydrophobic backbone with side chains ending in hydrophilic sulfonic acid groups. (1) In redox flow battery application, it conducts H+ while blocking vanadium ions to store energy. (2) In electrolyzer application field, it conducts H+ to produce green hydrogen or hydrocarbon from water and CO2. (3) In fuel cell application field, it conducts H+ from anode to cathode to generate power.

The economic PFSA membranes can be great alternatives to the expensive Nafion counterparts.
